HELEN M. DECKER, OF NEW YORK, N. Y.

FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 258,028, dated May 16,1882.

Application filed March 14, 1882.

To all whom it may concern:

Be it known that I, HELEN M. DEoKEa, of the city, county, and State ofNew York, have invented a new and Improved Fire-Escape, of which thefollowing is a full, clear, and exact description.

Myinventiou relates to that class of fire-escapes which are notpermanently fixed to the building, but are adapted to be attached to thewindowsill in case offire from the inside ofthe building or upperapartment, furnishing a ladder for the descent of the inmates thereof;and it seeks to provide a cheap and efficient fire-escape of thischaracter which may be quickly and easily put in position for use, andwlhich may he applied to all forms of windowsi ls.

My invention consists principally'ofa suitable metal plate, to whichtheladderis attached, and of a elamp-plate adapted to come against theinside of the window-sill, the two plates being connected together by ascrew-threaded bar or rod carrying a clamping-wheel which may bequicklyand easily turned for clamping the plates to the window-sill.

My invention further consists of a block to be used in connection withthe clamping-plates and screw-rod when the escape is to be used onsloping window-sills for elevating the es cape, and also in theconstruction, arrangement, and combination of parts, all as hereinafterdescribed.

Reference is to be had to the accompanying drawings, forming a part-ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents my new and improved fire-escape, in front elevation,as it appears when in position for use; and Fig.2represents the same inside elevation, the wall of the" building and the supporting-block beingshown in section. r

A represents the outside plate, which is by preference made with the twocurved arms a a, to which the ropes b b ofthe ladder B are attached. 0represents the inside clamp-plate;

.1), the screw rod or bar; and E represents the block which is placedupon the screw rod or bar I), for supporting the outer end of the bar Dwhen the escape is attached to-sloping window-sills, so that the bar Dwillhe held in about horizontal position, as shown in the drawings. a

Upon the inner-end of the screw rod or bar D is placed the hand-wheel F,for clamping the plate 0 firmly against the Window-sill'for firmlyattaching the escape to the sill, so that a perder cannotdetach theescape from the sill, andthe wheel F will be of such size that it willreach down upon the clamp-plate O sufficient distance to clamp it firmlyagainst the sill, and

so that the escape can be attached quickly and the clamp-plate screwedagainst the sill with a great deal of force.

It will be seen that by this construction of the escape, when attachedto the window-sill, it is perfectly safe. and secure, and will in nomanner mar the window-sill, so that no repairs will be needed in casethe fire is put out. Besides these advantages, the device is very cheapof construction, and when not in use can be stowed away in very smallspace.

Havingthus described my in vention,I claim as new and desire to secureby Letters Patent- 1. The fireescape herein shown and described,consisting of the plate A,to which the ropes b b of the ladderareattached, the clampplate 0, and the screw-rod D,and hand-wheel F,substantially as set forth.

2. In combination with the plates A and 0, rod D, and wheel F, the blockE, substantially as and for the purposes set forth.

HELEN M. DECKER.
